Abstract :
This paper describes a simple voltage regulator that allows contactors to ride through power line disturbances such as sags and dropouts. The voltage regulator protects critical equipment in continuous process industries and prevents loss caused by downtime. The voltage regulator is inexpensive and easily retrofitted into existing installations. A field trial of the voltage regulator has been successfully completed
